1 Claim. (01. 312-50) UNITED STATES PATENT OFFICE This invention relates to improvements in sheet-paper cabinets; the object of this invention is to provide a cabinet in which a supply of paper may be easily and quickly installed by the turn of a handle and at the same time automatically spread and arranged so that the sheets may be Withdrawn, one at a time, without disturbing the balance of sheets remaining.

A speedy, accurate and clean means is thus provided for the handling of sheet paper, used in offices and other lines of industry.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described in the appended claim with the accompanying drawing in which:

Figure 1 is a plan View of the invention, with paper removed from the right half to show interior parts.

Figure 2 is a side elevation, with parts of the side broken away for interior inspection.

Figure 3 is a front elevation of Figure 4, with the paper removed, and the cover l0, folded as in Figure 2, a portion in section, through lines 33, Figure 1.

Figure 4 is a side elevation, with a portion of the side broken away to show position of parts with sheets in place, prior to being drawn into cabinet.

Figure 5 is a perspective view of the tray, or sheet-holder, showing the hinges attached, and the cardboard sheet secured to bottom of tray.

Figure 6 is a plan of a section of the tray and the shaft, showing the relative positions of the sheet-paper gripping device.

Figure 7 is a side elevation of Figure 6.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral I indicates the cabinet in a general Way, with a hinged cover ID, in two sections, hinged at 20 between the sections, so that it may be folded back to View the interior of the cabinet. It is also hinged to the center top of the cabinet by hinges 20, and is shown open and folded back in Figure 2, and in closed position, by dotted lines in the same figure. The sides 25, are attached to a rectangular base, and as shown in elevation in Figure 2, have the back portions raised and semi-circular, to conform in shape to a stack of sheet paper coiled at one end within the cabinet, the front portions of the sides are raised sufliciently to enclose said stack of sheet paper lying fiat. The cover, when closed, rests on the edges of the lower front portion of the sides. The raised semi-circular sides have narrow recesses on the inside edges in which a transparent covering I1, is placed and held in position by means of narrow metal strips M. The purpose of this transparent covering is to give the operator a view of the mechanical gripping device, when inserting a new stack of paper. The bottom of the cabinet has a recess to facilitate the handling of paper, this recess [6, is shown in Figures 1 and 2; in Figure 1, by dotted lines.

Two wedge-shaped pieces "I, covered on top with thin felt 21, support the free sheet ends and prevent them slipping forward. A shaft 2, centrally located through the semi-circular portion of the sides, rotates in bearings 23, by means of a handle 4, attached to the shaft on the outside of the cabinet as shown in Figure 1. Collars 22, fixed to the shaft keep it in place, short crank levers l5, also fixed to the shaft, are coupled to clamping levers 9, by means of connecting links H. These clamping levers, 9, are pivoted on hinges 8, of tray or paper-holder 5, the position of the hinges and tray design is shown in Figure 5, in perspective.

A circular disc 3, is free to revolve on shaft 2, Washers 2|, and pins through the shaft keep' it centrally located. The purpose of this disc 3, is to prevent the sheets buckling when curved, and assists in drawing sheets within the cabinet to the right position in relation to the Wedges 1.

The tray 5, is free to move on shaft 2, within certain limits, determined one way, by the stack of sheet paper, and clamp levers 9, and the other way, by a projection 28, on clamp levers 9, coming in contact with the body of the tray, as shown in Figure 6, in side elevation.

In Figure 5, a sheet of cardboard I8, fixed to the bottom of tray 5, is to prevent the sheets slipping when gripped for turning.

The wedge-shaped piece l3, acts as a brace to sides 25. Another brace I2, is provided, which also acts as a stop for tray 5, at the end of its circular movement.

A light weight 26, in the form of a strip of metal plate, with a length equal to the width of the sheet paper used, with its back edge hingedly connected to the underside of stop l2, and with the front edge rounded and resting on the paper, is provided to hold the sheets down. When the fresh supply of sheets is installed in the cabinet, this weight is raised and held up with the fingers.

The operation of recharging the cabinet is as follows:

The tray 5, is turned, by means of handle 4, to the position shown in Figure 4, and held against the edge of the board 29, on which the sheets rest. In this position, the clamping levers 9, are raised so that the sheets may enter the traythis may be clearly seen through the transparent covering II; the weight 28, is raised, held up, and the stack of papers or sheets inserted. The handle is then turned, as indicated by the arrow in Figure 4, causing levers 9, to grip the sheets securely and then revolve the tray, drawing the sheets with it, around the disc 3, until stop I2, is reached. The free ends of the sheets will then be arranged correctly on wedges I, as shown in Figure 2. Handle 4, is now turned in the opposite direction, causing levers 9, to release their grip on the sheets; the

projections 28, on levers 9, now come in contact with the body of tray 5, and turn it in the same direction until the outer circle of sheets or cardboard l8, touches and comes to rest against the inside of the cabinet, shown by dotted line, 24, Figure 2. In this position, the grip on the sheets is released, and the inner circle of sheets loosened up, so that they may be easily withdrawn, one at a time as required.

The tray is held and stays in this position, by the weight of the paper on cardboard L8, which is attached to the tray. Partly uncoiling the sheets does not disturb the free ends of the sheets resting on wedges I.

The projections 28, on levers 9, keep handle 4, in position shown in Figure 2.

The recharging of the cabinet'is easily and speedily accomplished, with accurate results, in

a few seconds by this mechanical means.

What I claim as my invention is: V A sheet-paper cabinet or container comprising a rectangular base, with sides attached, the rear portion of the sides being raised in semi-circular shape to conform to a stack of sheet-paper adapted to be coiled at the rear end within the cabinet and with the front end of the sides being raised sufficiently to enclose said stack of sheet-paper lying fiat; a transparent covering extending from the base at the rear end over the semi-circular portion of the sides; a hinged lid in two sections covering the front lower portion of the cabinet; a shaft rotatably mounted through l the centre of the raised rear ends of the sides and extending through one side and having a handle attached on the outside of the cabinet; a tray or sheet-paper holder designed to receive the ends of a stack of sheet-paper, the ends of said tray being extended and connected loosely to said shaft and free to rotate around said shaft within the cabinet; paper-gripping levers pivoted on said tray and connected by links to levers rigidly attached to said shaft and operable by said handle to holdsheets securelyin said tray; a disc loosely mounted, on said shaft centrally of the width of the cabinet; laterally spaced felt-covered wedge-shaped pieces attached to said base in the front portion of the cabinet; whereby a stack of sheets may have an end thereof inserted in the tray, the handle rotated to cause the gripping levers to secure the stack to the, tray and rotate the tray to coil the gripped end of the stack around the disc and arrange the free edges'of the sheets of the stack in inclined position on said wedgeshaped pieces, and rotated in the opposite direction to release the stack from the tray so that the sheets may be withdrawn one by :one from the cabinet.
